On 27 February 2025, National Grid Ventures confirmed that the grid connection agreement for the Nautilus interconnector at Leiston in Suffolk had been removed in coordination with the independent National Energy System Operator (NESO). This removal took Nautilus off the interconnector register and confirmed that the project would not be built in Suffolk nor would the Leiston connection agreement be used for any alternative project, with Nautilus instead proceeding towards connection at the Isle of Grain in Kent.
